Floodplain Information

The Engineering Division is responsible for the maintenance and enforcement of the City's floodplain and floodway ordinances as mandated by the Federal Emergency Management Agency's (FEMA) National Flood Insurance Program (NFIP). The City Engineer operates in the capacity of the Floodplain Administrator.

Since Conroe participates in FEMA's NFIP, you are entitled to a premium discount. For more information on federal insurance and the premium discount, call your insurance company and refer them to this webpage or our annual Floodplain Notice and Flood Safety Information Brochure. Planning early is essential because it normally takes 30 days after purchase for a flood insurance policy to go into effect.

The 100-year floodplain is the land that will be covered by the 100-year flood. The 100-year flood is a standard used by the NFIP for floodplain management and to determine the need for flood insurance.

The term "100-year flood" is misleading. It is not the flood that will occur once every 100 years. Rather, it is the flood elevation that has a 1% chance of being equaled or exceeded each year. Thus, the 100-year flood could occur more than once in a relatively short period of time.

Please be aware that people outside of the 100-year floodplain are free of regulatory requirements, but not of risk. Federally-backed flood insurance also is available to people outside of the 100-year flood zone.

We are confident that the resources on this page and others will help you stay Flood Smart!
